Phaes Ⅱ Study of Golidocitinib-Pegaspargase-PD-1 Antibody First-Line for Advanced ENKTL

A Single-Arm, Open-Label Phase II Clinical Study to Evaluate the Safety and Efficacy of Golidocitinib in Combination With Pegaspargase and Anti-Programmed Death-1 (PD-1) Monoclonal Antibody as First-Line Therapy for Advanced Extranodal Natural Killer/T-Cell Lymphoma (ENKTL)

Extranodal natural killer/T-cell lymphoma (ENKTL) is an aggressive non-Hodgkin lymphoma with poor prognosis in advanced stages, with a 5-year overall survival (OS) rate of less than 30% despite asparaginase-based regimens. Preclinical and clinical evidence suggests that PD-L1 is highly expressed in ENKTL, and PD-1 inhibitors show promising activity, while JAK1 inhibitors (e.g., golidocitinib) can reverse PD-1/PD-L1 inhibitor resistance and enhance anti-tumor immunity. This phase II study aims to evaluate the safety, tolerability, and anti-tumor activity of golidocitinib combined with pegaspargase and anti-PD-1 mAb as first-line therapy for advanced treatment-naive ENKTL, providing a novel therapeutic option for this patient population.

   Measurable lesion: Lymph node ≥1.5 cm (long axis) × ≥1.0 cm (short axis); extranodal lesion ≥1.0 cm (long axis); if the only measurable lesion was previously irradiated, radiological progression after radiotherapy is required.

   Evaluable lesion: FDG-PET uptake higher than liver in lymph nodes or extranodal sites, consistent with lymphoma.

6. ECOG performance status 0-2.

   Adequate organ and bone marrow function (without supportive care within 14 days):

   Liver function: Total Bilirubin (TBIL) ≤1.5×ULN (≤3.0×ULN for Gilbert syndrome or liver involvement); Alanine Aminotransferase (ALT)/Aspartate Aminotransferase (AST) ≤2.5×ULN (≤5.0×ULN for liver involvement).

   Renal function: Serum Creatinine (Cr) ≤1.5×ULN or Creatinine Clearance Rate (Ccr) ≥50 mL/min (Cockcroft-Gault method).

8. Left Ventricular Ejection Fraction (LVEF) ≥50% by MUGA or echocardiogram.
9. Resolution of acute toxicities from prior therapies to ≤Grade 1 (CTCAE v5.0) or baseline; irreversible Grade 2 toxicities (e.g., neuropathy, alopecia) are allowed if not worsening.
10. Women of Childbearing Potential (WOCBP) must have negative serum pregnancy test within 7 days of first dose; WOCBP and male partners must use effective contraception from ICF signing to 6 months after last study drug dose.

Exclusion Criteria:

1. Aggressive NK-cell leukemia or ENKTL in leukemic phase.
2. Concurrent hemophagocytic syndrome.
3. Lymphoma involvement of central nervous system (CNS) or meninges.
4. History of other malignancies within 5 years (except cured localized tumors: e.g., basal/squamous cell skin cancer, in situ prostate/cervical/breast cancer).

5. Prior therapy:

   Allogeneic hematopoietic stem cell transplantation (HSCT) within 5 years (allowed if >5 years with no graft-versus-host disease).

   Autologous HSCT within 3 months. Prior JAK/STAT3 inhibitors. Concurrent use of strong CYP3A inducers/inhibitors (unable to discontinue 1 week before first dose).

   Concurrent vitamin K antagonists, antiplatelet agents, or anticoagulants (unable to discontinue 1 week before first dose).

   Systemic glucocorticoids or immunosuppressants within 14 days (local/ocular/inhaled/nasal glucocorticoids or short-term ≤7 days for prophylaxis allowed).

   Cytotoxic chemotherapy within 21 days. Systemic anti-tumor therapy (including mAbs, immunotherapy) within 4 weeks. Major surgery within 6 weeks or radiotherapy within 90 days. Toxin/isotope-antibody conjugates within 10 weeks. Investigational drugs within 30 days.

   Active infections:

   HIV infection. Active chronic hepatitis B (HBsAg positive with HBV DNA >2500 copies/mL or 500 IU/mL) or hepatitis C (HCV RNA positive). HBV carriers with controlled HBV DNA and cured HCV are allowed; HBsAg-positive patients require monthly HBV DNA monitoring and prophylactic entecavir until 12 months after anti-tumor therapy.

7. Active autoimmune diseases requiring systemic therapy within 2 years (allowed if inactive for 2 years; hormone replacement therapy for hypothyroidism/diabetes is allowed).
